Every API integration ages slowly over time, and eventually has a 'retirement date' lurking.
VIDEOLIGHTBOX DEPRECATED API CODE
Someone reads the API docs for a service's endpoints, writes some code to get things connected, and boom, the integration is born There's only one problem. Every API integration comes to life the same way. Pluto Identifies Deprecated Kubernetes FilesĮnter Pluto. API Lifecycle, Versioning, and Deprecation.
VIDEOLIGHTBOX DEPRECATED API UPGRADE
We wanted a way to provide this info ahead of time so that deployment processes could be addressed before the upgrade happens. When you have a lot of applications deploying to your Kubernetes cluster (like many of our clients), a cluster upgrade to version 1.16 could break deployment processes, potentially across hundreds of repositories. This makes it impossible to tell which version you actually deployed to the server, causing problems when you upgrade.
You’ll notice that all of these commands returned the same object, but with the apiVersion set to whatever you asked for in the request.
$ kubectl get rbac-manager-o yaml apiVersion: extensions/v1beta1 kind: Deployment metadata: name: rbac-manager. $ kubectl get deployments.v1.apps rbac-manager -o yaml apiVersion: apps/v1 kind: Deployment metadata: name: rbac-manager. $ kubectl get rbac-manager -o yaml apiVersion: apps/v1beta2 kind: Deployment metadata: name: rbac-manager. For example, while running Kubernetes 1.15.X you can run the following commands to see Deployments from various API versions: $ kubectl get rbac-manager -o yaml apiVersion: apps/v1beta1 kind: Deployment metadata: name: rbac-manager. The kube-apiserver is flexible and provides the same info about a given resource type regardless of the API version specified in the request. We decided to write an open source utility, Pluto (named after the deprecated planet), to solve this problem. It's painful to find deprecated versions and you'll be blocked from upgrading to 1.16 until they've all been updated. This has led to many conversations around the Kubernetes 1.16 upgrade where multiple deprecated versions of the Deployment resource are removed (among others, read more here). When this happens, the older versions get deprecated and will eventually be deleted. It allows the Kubernetes team to easily release new features to alpha and beta API paths and graduate them to stable paths once they’ve been battle-tested. The Kubernetes API versioning scheme is great for developers. Pluto is an open source utility to help users easily find deprecated Kubernetes API versions in their Infrastructure-as-Code repositories and Helm releases.
